Hi,

For some time, I'm seeing a tiled output like:
http://www.fi.muni.cz/~xslaby/sklad/panics/bad_tile.png

This happens sometimes when I open selected pages in firefox. Like
maps above.

Currently I'm running 3.2.0-rc3-next-20111130. This started appearing
after I switched to desktop fx. Will anything from the debugfs help to
track this down? Or better to report this to freedesktop.org?

Please test the patch Chris already replied with to your first mail. It
might fix your issue here (if it's just a fence being stolen a bit too
early). If that does not help, I'll have to stare at the picture some more
to decode the type of tiling/swizzling going on. Maybe different pictures
of corruptions might help for that.

Hi, I'm already running a kernel with that patch. The artefacts are
still there though.

Something is pretty decently broken here. Can you please file a bug at
freedesktop.org against the i915 drm? A few other things
- Can you check whether upgrading the ddx to 2.17 fixes this? Also please
  attach your Xorg.log and full dmesg.
- Please grab intel-gpu-tools.git from

http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/

  and attach the output of tools/intel_reg_dumper to the bug report.
- If you're using swap, can you check whether disabling it works around
  the issue?

And please put me as the assignee of the bug.

Thanks, Daniel
